This article is taken from a talk I gave at the 29th Annual Meeting of the Doctors for Disaster Preparedness in Albuquerque last week, on the controversial subject of saturated fats. Some of the slides that I used for this talk are put in here.

The medical establishment and government health authorities say that consumption of saturated animal fats is bad for us and causes heart disease. According to the lipid hypothesis - the label used for the diet-cholesterol theory of heart disease - saturated fats raise serum cholesterol levels, and high blood cholesterol causes obstructive plaques to form in arteries, called atherosclerosis. This pathologic process causes coronary heart disease and the need for coronary artery bypass surgery, which is what I do.

The food industry makes trans fats. They do this by shooting hydrogen atoms into polyunsaturated vegetable oils. This straightens out the fatty acid molecules and packs them closer together, giving vegetable oil so treated a solid texture like lard. Trans fats are used to make margarine, with yellow bleach added so it looks like butter. They are also used prolong the shelf life of bakery products, snack chips, imitation cheese, and other processed foods.

Fats have a string of 3 to 22 carbon atoms. The carbon atoms of saturated fats have a full complement of hydrogen atoms attached to them. Unsaturated fats lack a full complement of hydrogen atoms. Artificially created trans fats have hydrogen atoms that wind up being located on opposite sides of the carbon double bond, which straightens the molecule out and makes it mimic saturated fat.

Crisco

A hundred years ago less than one in one hundred Americans were obese and coronary heart disease was unknown. Pneumonia, diarrhea and enteritis, and tuberculosis were the most common causes of death. Now, a century later, the two most common causes of death are coronary heart disease and cancer, which account for 75 percent of all deaths in this country. There were 500 cardiologists practicing in the U.S. in 1950. There are 30,000 of them now - a 60-fold increase for a population that has only doubled since 1950.

In 1911, Procter and Gamble started marketing Crisco as a new kind of food. The name Crisco is derived from CRYStalized Cottonseed Oil. It was the first commercially marketed trans fat. Crisco was used to make candles and soap, but with electrification causing a decline in candle sales, Procter and Gamble decided to promote this new type of fat as an all-vegetable-derived shortening, which the company marketed as a "healthier alternative to cooking with animal fats." At the time Americans cooked and baked food with lard (pork fat), tallow (beef and lamb fat), and butter. Procter and Gamble published a free cookbook with 615 recipes, from pound cake to lobster bisque, all of which required Crisco. The company succeeded in demonizing lard, and during the 20th century Crisco and other trans fat vegetable oils gradually replaced saturated animal fats and tropical oils in the American diet.

Evidence Supporting the Lipid Hypothesis

Rabbits, Cholesterol, and Atherosclerosis

In 1913 a Russian physiologist fed high doses of cholesterol to rabbits and showed that cholesterol caused atherosclerotic changes in the rabbit's arterial intima like that seen with human atherosclerosis. Over the ensuing decades other investigators did atherosclerosis research on cholesterol-fed rabbits, which they cited in support of the diet-cholesterol theory of heart disease.

Framingham Heart Study

In 1948, government-funded investigators began following some 5,000 men and women in Framingham, Massachusetts to see who developed coronary heart disease. They found that people with elevated cholesterol were more likely to be diagnosed with CHD and die from it.

Six years later the American Heart Association began promoting what it called the Prudent Diet, where "corn oil, margarine, chicken, and cold cereal replaced butter, lard, beef, and eggs."

Ancel Keys Six-Country and Seven-Country Studies

Ancel Keys, the father of K-rations for the military, published a study in 1953 that correlated deaths from heart disease with the percentage of calories from fat in the diet. He found that fat consumption was associated with an increased rate of death from heart disease in the six countries that he studied.

He followed this up with a more detailed Seven Country Study published in 1970, using three of the countries that were in the original six-country study - Italy, Japan, and the U.S. - and four other countries - Finland, Greece, The Netherlands, and Yugoslavia. This study further cemented the association of fat consumption and death from heart disease, which led to the McGovern Report.

McGovern Report

The U.S. Senate Select Committee on Nutrition and Human Needs, chaired by Senator George McGovern, released, in 1977, its "Dietary Goals for the United States," designed to reduce fat intake and avoid cholesterol-rich foods. These dietary goals became become official government policy.

Further Developments

McDonalds and the Center for Science in the Public Interest

Next, in 1984 the Center for Science in the Public Interest, a consumer advocacy group, joined the fray and started to coerce fast-food restaurants and the food industry to stop baking and frying food with animal fats and tropical oils. McDonalds fried its French fries with beef fat and palm oil. That's why they tasted so good. But the Center for Science in the Public Interest's well-orchestrated saturated fat attack coerced McDonalds and other fast-food chains to switch to partially hydrogenated, trans-fat vegetable oil.

Adhering to the now well established low fat dogma, the U.S. Department of Agriculture, in 1992, published its Food Guide Pyramid. The "pyramid" arranges food in sections that convey the message, "Fat is bad" and "Carbohydrates are good." Carbohydrate-rich bread, cereal, rice, and pasta fill the large bottom space. and are to be consumed in abundant amounts, "6 - 11 servings" a day. Further up, as the pyramid narrows, fruit, which is also high in carbohydrates, is accorded "2 - 4 servings"; whereas the portion that includes meat, poultry, fish, dry beans, eggs, and nuts is allowed only "2 - 3 servings." Fats and oils are placed in the small top portion of the pyramid and labeled "Use sparingly."

Dietary Guidelines for Americans 2010

Beginning in 1980, the U.S. Department of Agriculture and Department of Health and Human Services has published every five years an updated Dietary Guidelines for Americans. The most recent one, published in December 2010, recommends reducing saturated fat intake to 7 percent of caloric intake, down from its previously recommended 10 percent.

Meet the Fats

The USDA dietary guidelines and the American Heart Association group trans fats and saturated fats together and demonize them both as solid fats. The heart association's website has a "Meet the Fats" link where the bad fats brothers are Sat and Trans - saturated fats and trans fats. The better fats sisters are Poly and Mon - polyunsaturated and monounsaturated fats.

Swedish Heart Institute, Seattle and Dean Ornish

Indoctrinated in low-fat dogma by health organizations, nutrition authorities, and the government, I would instruct my heart surgery patients to eat a low fat diet, telling them to cut all the fat off their meat and not eat more than one egg a week. And following the USDA food pyramid I did not express any concerns about how much carbohydrates they might consume, from starch in bread, pasta, rice, and potatoes and sugar in fruit, fruit juices, pastry, and sodas.

When I was the director of the heart institute at Swedish Medical Center in Seattle in the 1990s I looked into establishing a Dean Ornish Program for Reversing Heart Disease at Swedish. The Ornish Program limits fat intake to less than 10 percent of calories in the diet, with, as one study shows, only 1 percent saturated fat. I had a cardiologist at Swedish accompany me to New York to visit the leading Dean Ornish Program there. We came back and recommended that Swedish establish one in Seattle.

I was wrong. Several years later, after leaving Swedish and rejoining the faculty the University of Washington, I came upon an article by Dr. Mary Enig and Sally Fallon titled "The Oiling of America" that was published in the magazine Nexus in 1999. It stimulated me to look more carefully into this subject.

Sleeper

Oscar Wilde said "Life imitates art." He noted that "Life imitates art far more than art imitates life." In his film Sleeper Woody Allen plays Miles Monroe, part owner of the Happy Carrot Health Food Restaurant in Greenwich Village. He was cryogenically frozen in 1973 after a botched peptic ulcer operation done at the now closed St. Vincent's Hospital. Two hundred years later scientists wake him up and revive him.

Scene from movie

In a scene from this movie (shown at the meeting), the two scientists have this exchange. Dr. Aragon: "Has he asked for anything special?" Dr. Melik: "Yes. This morning for breakfast he requested something called wheat germ, organic honey, and tiger's milk." Dr. Aragon: "Oh yes. Those were the charmed substances that some years ago were felt to contain life-preserving properties." Dr. Melik: "You mean there was no deep fat? No steak or cream pies or hot fudge?" Dr. Aragon: "Those were thought to be unhealthy, precisely the opposite of what we now know to be true." Dr. Melik: "Incredible!" The YouTube title of this scene is Woody Allen's 1973 film Sleeper may accurately portray healthy eating in the future, (available here).

Tiger's milk is said to be America's original carbohydrate-rich, protein-rich nutrition bar. It was popular in the 1970s and is still sold. I got this one from Amazon.com (that I show at the meeting). As this cinematic work of art predicts, in 2173 deep fat, steak, cream pies, and hot fudge will have replaced wheat germ, organic honey, and tiger's milk as health foods.

But if life does imitate art, what about all the evidence that shows saturated fats and cholesterol clog arteries and cause atherosclerosis?

Evidence Against the Lipid Hypothesis

Feeding Cholesterol to Omnivores Does Not Cause Atherosclerosis

Plants do not contain any cholesterol. Animals are the only source of cholesterol, and herbivores do not eat animal products. Rabbits, being a herbivore, are not designed to digest animal fat and cholesterol, so when it is fed high doses of cholesterol one should not be surprised if the cholesterol winds up getting stuck in any part of the poor rabbit, including its blood vessels. Feeding high doses of fat and cholesterol to omnivores, like rats and dogs, does not produce atherosclerotic lesions in them.

Other Countries with CHD-Death and Fat Consumption Data

Evidence against fat wilts upon close scrutiny. In his Six Country Study, Ancel Keys ignored data available from 16 other countries that did not fall in line with his desired graph. If he had chosen these six other countries [on the left side], or even more strikingly, these six countries [on the bottom right] he could have shown that increasing the percent of calories from fat in the diet reduces the number of deaths from coronary heart disease.

22 Countries with Such Data including four other groups of people

If Keys had included all 22 countries in his study, the result would have been a clutter of dots like this.

In fact, it turns out that people who have highest percentage of saturated fat in their diets have the lowest risk of heart disease.

Diets in People with the Lowest Risk of Heart Disease - Masai, Inuit, Rendille, Todelau

The diet of the Maasai tribe in Kenya and northern Tanzania consists of meat, milk, and blood from cattle. It is 66 percent saturated fat.

The diet of Inuit Eskimos in the Artic, consisting largely of whale meat and blubber, is 75 percent saturated fat; and they live long healthy lives free of heart disease and cancer.

The Rendille tribe in the Kaisut Desert in NE Kenya subsist on camel milk and meat, and a mixture of camel milk and blood, known as "Banjo." Their diet is 63 percent saturated fat.

The Tokelau live well, without cardiologists, on three atoll islands that are now a territory of New Zealand. Their diet consists of fish and coconuts, which is 60 percent saturated fat.

Like these groups of people around the world, breast-fed infants in developed first-world countries also have a diet that is high in saturated fats. The fat in human mother's milk is 54 percent saturated fat.

The Hunter-Gatherer Diet

The study referenced here, published in the American Journal of Clinical Nutrition, is considered to be the most comprehensive analysis done on the Paleolithic hunter-gather diet. Anthropologists have assessed the diets of 229 hunter-gather populations that survived into the 20th century and can be viewed as surrogates for our Paleolithic, Stone Age ancestors.

When they can get it, these modern-day hunter-gatherers consume high amounts of animal food, which can make up to 85-100 percent of their calories, like the Maasi, Inuit, and Rendille peoples. They eat virtually all of the fat on the animal, including its organs, tongue, bone marrow, and brain. Other carnivores do the same thing. Lions, for example, will eat the organs and fat of their kill and leave the lean muscle meat for scavengers.

Since hunter-gatherers do not engage in agriculture, they have no corn, rice, or wheat to eat. They obtain only a low amount of carbohydrates from wild plants, gathering seeds, nuts, roots, tubers, bulbs, and fruits from them.

The Human Diet Throughout History

The Paleolithic Era, or Stone Age, lasted two-and-a-half million years, beginning with our human ancestor Homo hablis, and progressing through a succession of species to ours, Homo sapiens, which has existed for some 200,000 years.

The Agriculture Age began approximately 10,000 years ago and during this time, through 500 generations, carbohydrate consumption gradually increased. Even so, at the beginning of the Industrial Revolution 250 years ago, sugar consumption was one-fifth of what it is today. Now we are eating a greatly increased amount of carbs in cereal grains, dairy products, beverages, refined sugar, and candy, along with processed vegetable oils and dressings that did not exist in our diet for 99.9 percent of human history. During this time the human genome became adapted to follow a high-fat, low-carbohydrate diet. Nevertheless, health authorities today say that we should do the opposite and follow a low-fat, high-carbohydrate diet.

As calories, fat and carbs are interchangeable, protein less so. One can eat and digest only so much protein. When the protein content of the diet exceeds 35 percent of calories, nausea, diarrhea, and weakness ensue. These symptoms disappear when protein is dropped to 20-25 percent of calories.

YouTube on Ancel Keys

The new social media of Facebook, Twitter, and YouTube is not only helping to overthrow dictators and autocratic regimes but also wrong medical dogmas. This one, titledBig Fat Lies (shown at the meeting), exposes the chicanery Ancel Keys practiced in his work (available here).

The Framingham Study 30-years on

But what about the Framingham Study? In 1987, in the Journal of the American Medical Association Framingham Study investigators reported these two important findings: 1) Over age 50 there is no increased overall mortality with either high or low serum cholesterol levels, and 2) In people with a falling cholesterol level (over the first 14 years of the study), for each 1% mg/dl drop in cholesterol there was an 11 percent increase in all-cause mortality over the next 18 years. (JAMA 1987;257:2176-2180)

Contrary Long-term Findings of the Framingham Heart Study

Then, in 1992, in the Archives of Internal Medicine, the third director of the study, Dr. William Castelli, reported: "In Framingham, Mass., the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower the person's serum cholesterol" [emphasis in original]... We found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories, weighed the least, and were the most physically active." (Arch Int Med 1992;152:1271-2)

Most doctors have not heard about these findings because medical organizations, notably the American Heart Association, government agencies, and the pharmaceutical industry have ignored them. After all, prescribing statin drugs to lower cholesterol is a $25 billion/year industry.

The Politics Behind the McGovern Report

What about our government and the McGovern Report? The YouTube video titled "The McGovern Report" (shown at the meeting) deals with it in a pithy way (available here).

Mary Enig, Ph.D., a researcher at the University of Maryland, is interviewed in the video. In 1978, she was the lone whistleblower warning people about the dangers of trans fats. The medical establishment, government, and the food and drug industry belittled and ignored her findings that trans fats interfere with critical enzyme systems in the body and suppressed these findings for 25 years. As evidence of their dangers continued to grow the FDA, finally, in 2003, announced that beginning in 2006 the food industry must display how much trans fat the product contains on its nutrition facts label. Having ignored the subject since its inception in 1980, the government's 2005 Dietary Guidelines for American at last warned them to restrict their consumption of trans fats. In 2006 New York became the first city in the nation to ban trans fats in restaurant food.

Saturated Fat and Heart Disease

Evidence that the McGovern Committee did not have in the 1970s is this 2005 report of European Cardiovascular Disease Statistics.

They show an inverse correlation with saturated fat consumption and rate of heart disease. Countries with the lowest consumption of saturated fat have the highest rates of heart disease. Georgia, Tajikistan, Azerbaijan, Moldova, Croatia, Macedonia, and Ukraine all have a saturated fat consumption that is less than 7.5% of calories, which is what the USDA and American Heart Association recommend, but their death rate from heart disease is quite high. Austria, Finland, Belgium, Iceland, the Netherlands, Switzerland, and France have high levels of saturated fat in their diet and low rates of heart disease. France, with the highest fat consumption, has the lowest rate of deaths from heart disease amongst these 14 European countries.

Reasons Why Saturated Fats Are Good For Us

The Biologic Importance of Saturated Fat

There is good reason why 54 percent of the fat in mother's milk is saturated fat. Cell membranes need saturated fatty acids to function properly and be "waterproof." The heart prefers saturated long-chain 16-carbon palmitic and 18-C stearic acid (over carbohydrates) for energy. Bones need them to assimilate calcium effectively. They protect the liver from the adverse effects of alcohol and medications like Tylenol. Lung surfactant is composed entirely of saturated 16-C palmitic acid, and when present in sufficient amounts prevents asthma and other breathing disorders. Saturated fats function as signaling messengers for hormone production.

They play an important role in the immune system by priming white blood cells to destroy invading bacteria, viruses and fungi, and to fight tumors. And medium-chain 12-C lauric acid and 14-C myristic acid (in butter) kill bacteria and candida fungus.

Saturated fats signal satiety, so you stop eating because you feel full, lose fat, and maintain a normal weight.

The American Journal of Clinical Nutrition is a leading establishment medical journal that defends the lipid hypothesis. Even this journal has backed down and is now reporting cracks in the wall of diet-cholesterol-heart orthodoxy. A meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease does not support the notion that saturated fats increase the risk of coronary heart disease, stroke, or peripheral vascular disease.

And this journal also recently published a prospective cohort study of 53,000 women and men comparing their intake of carbohydrates and saturated fats and found that replacement of saturated fats with high glycemic index carbohydrates significantly increases the risk of heart attacks.

A Randomized Double-Blind Trial on the Effects of Coconut Oil on Abdominal Obesity

This trial, published in the journal Lipids, enrolled 40 women with a waist circumference > 35 inches. Twenty were randomized to take 30 ml - two tablespoons - of coconut oil a day (Group C) over a 12-week period. The other 20 took 30 ml soybean oil/day (Group S).

The Group C women taking the coconut oil exhibited a significant reduction in waist circumference (for the statisticians among us the P value was 0.005) with no change in the soybean Group S. And the only thing that the saturated fat-laden coconut oil did to cholesterol levels was to raise HDL cholesterol, the one that advocates of the lipid hypothesis call the "good" cholesterol. (Lipids 2009;44:593-601)

Eat Fat Lose Fat

Dr. Mary Enig and Sally Fallon, president of the Weston Price Foundation, have written a book titled Eat Fat Lose Fat: Lose Weight and Feel Great with Three Delicious, Science-based Coconut Diets. I highly recommend it. The fat content of coconut oil is 92 percent saturated fat, the highest saturated fat content of any food. I now start each day with two tablespoons of coconut oil.

Other Considerations

Roles Cholesterol Play

What about cholesterol? As with saturated fat, it is not a villain. On the contrary, cholesterol is critical for good health. It is an essential component in every cell in the body. Although few doctors know this, more than 20 studies have shown that elderly people with a high cholesterol blood level live longer than do those who have a low cholesterol blood level.

Cholesterol is the mother of hormones. It is converted into stress and sex hormones, like cortisol, testosterone, and estradiol, in the adrenal cortex. The liver turns cholesterol into bile salts needed for intestinal absorption of fats and the fat-soluble vitamins A, D, E, and K. And when exposed to UVB rays in sunlight or at a tanning salon, the skin turns cholesterol into vitamin D.

Cholesterol also is the body's fire brigade. It repairs damage to the body's tissues, particularly the damage in arteries inflammation does to cause atherosclerosis. Blaming cholesterol for atherosclerosis is like blaming firemen for the fire they have come to put out.

Along with saturated fats, cholesterol is also an integral component of cell membranes.

The brain and nerve tissue contain the highest concentration of cholesterol in the body. It is a key component in forming synapses - cell connections - needed for good mental functioning, learning, and memory.

If not cholesterol, then what causes heart disease?

Atherosclerosis is an inflammatory process brought on by eating too many carbohydrates and omega-6 vegetable oils. Stress plays a role and possibly also bacterial infection.

A deficiency of various vitamins shown here may also play a role in causing atherosclerotic heart disease, as may an excess or deficiency of various minerals.

U.S. Dietary Fat: Animal and Vegetable Sources 1909 and 1985

Over the past century, butter consumption has plummeted from 18 grams per person per day to 5 grams. Consumption of lard has dropped substantially while use of shortening has almost tripled. In 1909, shortening was a natural product made with coconut oil and lard. Shortening used today is made out of partially hydrogenated vegetable oil.

Consumption of margarine made with trans fats has gone up five fold, and vegetable oils, more than fifteen-fold. Along with trans fats, these often rancid vegetable oils are new to the human diet.

A good case can be made that these changes in fat-and-oil consumption over the last hundred years are the major cause of the epidemic of obesity, diabetes, heart disease, stroke, cancer, and learning disabilities in children. Observing the increasing use of vegetable oils during the 1940s and 1950s, a few physicians, notably Dr. Weston A. Price and Dr. Francis Pottenger, predicted that there would be increasing rates of such diseases.

Prevalence of Obesity among US adults 1950-2010

An epidemic of obesity has accompanied the adoption of a low-fat diet. With only 1 in 150 people obese when the century began, by 1950 nearly 10 percent of Americans were obese. Thirty years later, in 1980, it had risen to 15 percent. Then following publication of the U.S. Dietary Guidelines and its every-five-year updates, obesity in Americans has steadily risen. Now two-thirds of the American public is overweight, with more than one-third, obese. Today the average American weighs 30 pounds more that he or she did 100 years ago. American women weigh and average 167 pounds and men, 191 pounds.

There is solid evidence that this epidemic of obesity has resulted from replacing saturated fat in the American diet with carbohydrates and processed polyunsaturated vegetable oils.

Carbohydrate Consumption and Obesity

The rise in obesity parallels closely the rise in carbohydrate intake. As Gary Taubes shows in his book Why We Get Fat: and what to do about it, carbohydrates, not overeating or a sedentary life, are what make you fat. Eating fat and protein don't make us fat, only carbohydrates do.

The Primal Blueprint Carbohydrate Curve

This graph, in Mark Sisson's book The Primal Blueprint, compares carbohydrate intake with weight.

Consuming less than 150 grams of carbs a day enables one to maintain a stable weight. More than that and you gain weight. One burns more fat and will lose weight when carbohydrate intake is less than 100 grams a day. Unfortunately, Americans today consume between 300-500 grams of carbs a day.

The Epidemic of Diabetes

Over a 30-year period from 1980-2008 the prevalence of diabetes more than tripled. Now, in 2011, according to the National Diabetes Fact Sheet, 25.8 million children and adults in the U.S., 8.3 percent of the population, have diabetes; and 79 million people, based on their fasting glucose and hemoglobin A1c levels, are prediabetic.

Diabesity

Diabetes and obesity go together, so much so that these disorders are now being called "diabesity". Body mass index (BMI) is the commonly used measure for obesity, calculated by dividing one's weight in kilograms (Kg) by one's height in meters squared (Kg/m2). One is considered to be obese if the BMI ≥30, and morbidly obese with a BMI of ≥35.

People with a BMI ≥35 are 10 times more likely to develop diabetes in their lifetimes than those with a normal BMI of 18.5-25. The lifetime risk of diabetes is around 30 percent for people who are overweight with a BMI of 25-30, 50 percent for obese people with a BMI of 30-35, and around 70 percent for people who are morbidly obese.

Disease Trends and Butter Consumption

Consumption of butter has dropped precipitously while cancer and heart disease has soared. The rise in cancer and heart disease certainly cannot be blamed on high-saturated-fat butter.

A 12-ounce can of coke has ten teaspoons of sugar, which contain 42 grams of sugar, supplying 167 calories. A 20 ounce bottle has 17, and a 30 ounce bottle, 27 teaspoons of sugar. The average American drinks 600 cans (56 gallons) of soft drinks a year, up from 216 can in 1971. The average American teenager drinks 3 to 6 cans of soda a day!

One-third of our dietary sugar comes from sodas, and they have become America's number one source of calories.

Disasters

Disasters that may confront us can be divided into ones that are natural and those that are human made. The natural ones range from an earthquake to an impact event, like the one 65 million years ago where an asteroid six miles in diameter collided with the earth and wiped out the dinosaurs, and all other life forms larger than a small chicken.

Human-made disasters include political, economic, and martial types, a number of which Doctors for Disaster Preparedness has addressed. To this list must be added the nutritional disaster of a low-fat, high-carbohydrate diet.

Weapons of Mass Destruction

These trucks laden with soda pop serve as its weapons of mass destruction.

Health Benefits of a Low-Carbohydrate, High-Saturated Fat Diet

In addition to Eat Fat, Lose Fat, I recommend two more books that can help us reduce our carbohydrate intake. One is Life Without Bread: how a low-carbohydrate diet can save your life. It describes diets that limit carbohydrate intake to 72 grams a day, which is equivalent to 6 slices of bread. The other one isWhy We Get Fat: and what to do about it by Gary Taubes. Noting that meat, fish, and eggs contain no carbohydrates, he suggests that you can eat as much of them as you like, along with leafy green vegetables. (Try chicken salad wrapped in lettuce rather than as a sandwich between two slices of bread.)

The ideal caloric ratio between carbohydrates, fats, and protein is carbohydrates, 10-15 percent; proteins, 15-25 percent; and fats, 60-70 percent of calories, with the majority of them being saturated fats. Among the different kinds of fats, saturated fats and monounsaturated fats are good; except for omega-3 and a small amount of omega-6 essential fatty acids, polyunsaturated fats are bad in the high quantities that they are eaten in a Western diet, particularly industrially processed vegetable oils; and trans fats are terrible. Saturated animal fat is best obtained from grass-fed beef and pastured chickens, along with nitrate-free, additive-free bacon and sausage; and seafood from wild, not farm-raised, fish.

The Sacred Cow

Healthy milk and meat comes from contented cows on pasture, eating grass food that they are genetically designed to eat.

The "Efficient" Industrial Confinement Model

Confinement operations like these produce meat that is too high in omega-6 polyunsaturated fat and too low in vitamins. It being certified "organic" is not sufficient. The turkeys in the photo in the lower left can be sold as organic because they are "cage free"! The best meat to eat is that which is "Certified humanely treated" or "100% grass-fed/finished."

The Pastured Poultry Model

Pastured poultry produce eggs much richer in nutrients such as vitamins A and D and omega-3 fatty acids. Like with the turkeys so confined, organic eggs are produced mainly in barns. One wants to eat pastured eggs like those sold at a farmer's market.

Three types of eggs

The color of the yolk is an indication of the presence of nutrients. The pastured egg, with its dark orange color, is full of nutrients. The organic store egg less so. The supermarket egg, pale as it is, would be even whiter if the chickens weren't fed orange foods and dyes.

Confinement Butter vs. Grass-Fed Butter

The butter on the right was made from cream from cows on green pasture. The deep yellow color is indicative of high levels of omega-3 fats and fat-soluble vitamins. The butter on the left was made with cream from confined cows. Commercial butter like this has artificial color added to it so the consumer will not know that it is actually colorless.

Conclusion

Enjoy eating saturated fat but preferably from grass-fed animals.

For further reading on this subject, I recommend two articles, which are available online. One is the article that prompted me to question the lipid hypothesis. The second one is my now more enlightened view on this subject.

I did a podcast on the health benefits of a low-carbohydrate, high-saturated-fat diet on the Livin La Vida Low Carb Show. The show's host, Jimmy Moore, has titled it, "Cardiac Surgeon Dr. Donald Miller Tells Dr. Dean Ornish to Take a Hike." A link to it is here (and on my website).

Supporters of the orthodox view that saturated fats and cholesterol cause heart disease who dismiss these books, unread, bring to mind George Orwell's definition of orthodoxy: "Orthodoxy means not thinking, not needing to think." And Frank Zappa put it well when he said, "The mind is like a parachute, it works only when it is open." One needs to approach this subject with an open mind.

Reader Comments

BTW if people looked in my pantry, they'd be mortified...beef lard, bacon grease, palm shortening, coconut oil, etc...I'm thin as a rail, while my hubby who insists on staying away from fats is having weight problems...

is relative for every human being. It's a calories in-calories out equation. Eat as much as you want and whatever you want. The general rule is that as basically as you go up in age you can't burn as many as you when you did when you were young so you need less calorie intake. And a couple of hundred other factors that you have to find out for yourself. Worst thing though is stress. It can really mess you up.
